New description: [New technical field] The present invention relates to a fixed structure of a fan motor stator set, in particular to a first engaging portion of a fan seat and a second engaging portion of a stator set. Hook and snap fit to quickly and securely fix the fixed structure of the fan motor stator set. [Prior Art] Today, fans with cooling and cooling functions have become very important components in modern electronic products. From small portable computers to vehicles, there are many electronic devices, and these electronic devices often operate. Along with the high temperature, it affects its working performance, and even causes the electronic devices to shut down. Therefore, most of these electronic devices need to use a cooling fan to provide cooling to lower the temperature, so that the electronic devices can operate stably. Therefore, the reliability and durability of the above-mentioned cooling fan itself are also the key factors to ensure the stable operation of these electronic devices. Therefore, manufacturers of cooling fans today are not committed to developing more diverse fan-like plastics to meet various heat dissipation. demand. At the same time, the design of the cooling fan has been continuously improved to ensure the reliability and durability of the cooling fan. In addition, it is expected to be simplified in structure to reduce the cost of the material and assembly of the cooling fan. For example, 'When the stator and the fan seat of the cooling fan are installed 4 M^81224', it may be used for fastening or screwing elements, or it may be glued to fix or reinforce the mounting strength. . Please refer to the Chinese Patent Publication No. 566757, which discloses a conventional stator stator fixing structure, which comprises a sleeve copper (shaft tube) and a fixing buckle. The set of copper has all the slots. The fixing lug has a positioning portion and a latching portion, and the latching portion is embedded in the sleeve of the sleeve, and the positioning portion abuts against the top surface of the coil base of the motor stator to achieve the effect of fixing the motor stator. The problem to be solved by this conventional technique is that if the joint strength is insufficient during assembly, it is easy to cause the motor stator to fall off due to continuous vibration during long-term operation. However, the above-described heat radiating fan has another problem in production assembly. For example, additional fasteners will add additional material and assembly costs and complicate the assembly process; and the retaining clips are adjacent to the inner wall of the rotor housing of the motor.
